Building, testing, and deploying a Python web service using Zappa

We are going to create a simple hello world program as a microservice using Python's Bottle framework. Let's follow some basic steps to configure a small project using the Bottle framework:

1. First, we will create a new project directory named lambda_bottle_poc:

   $ mkdir lambda_bottle_poc

2. Let's create a virtual environment inside the lambda_bottle_poc directory:

   $ virtualenv env -p python3.6

3. Here is the basic hello world program using the Bottle framework:

Now it's time to deploy the program as serverless on AWS Lambda and expose the /hello API via API Gateway. In the previous chapter, we described the manual process to deploy the Python application, using AWS console and AWS CLI, which was a really big challenge.

But with the help of Zappa, all manual processes of the AWS console and AWS...
